Facebook bought Instagram for a bazillion, Digg sold itself for a Quizno's gift card, and countless startups are hoping to get copped too. But if you could make it happen, which company would buy out which?

I'd love to see Apple pick up the BBM division of RIM, the only wonderful slice in an otherwise feces-topped pizza, and use it to make iMessage as perfect as BBM has always been. Foursquare is also ripe for the picking, and mixing it into Apple Maps would make that beleaguered app super useful.
